In cigar rolling apparatus of the apron-rolling type and in which the portion of tobacco allotted for making the ller is thrust into a trough on the rolling table o-n which the rolling apron is located, a roller extending over .the table cooperates with the rolling apron for the purpose of forming the bunch. This roller is mounted on a suitably pivotally mounted lever support. In the preparation of a bunch the tobacco is provided with a wrapper. This must therefore be placed on the rolling apron, which is generally done by hand. As the wrapper must first of all be prepared (spread out and smoothed) before it can be applied, there is a relatively short time available for this operation which must be performed by one and the same person, and consequently the attendant does not allow the machine to run continuously, but stops it whenever a wrapper has to be applied and sets it in motion again when the operation is completed. With large plants of complicated construction, the wrapper-applying operation can be performed by purely mechanical means, for instance by means of a suction head which seizes the wrapper which is cut out on a table, likewise mechanically, and

then is guided in such manner that it forwards the wrapper to the depositing position. This, however, is an apparatus of very complicated construction and above all very expensive, because the control of the suction head is not simple and at the same time a means of control of the suction air current itself must be provided.

The object of the present invention is `to apply the wrapper by purely mechanical means while using machines of simple construction, i. e. small cigar-making machines.

This end is attained by providing the rolling apparatus with a special table on which the wrapper is placed in such manner that a controlled gripping member arranged on the support of the bunch roller, on the forward movement of the support, seizes the wrapper and on its backward movement, places it over the trough which receives the iiller tobacco.

In this manner the support of the bunch roller itself is utilized for applying the wrapper, so that by means of this already available swinging memer the wrapper can be applied mechanically without other intermediate members being provided, namely with ease, at the right moment and at the right place.

The invention is illustrated in the annexed drawings, in which:-

Fig. 1 is a vertical longitudinal section through the apparatus.

Fig. 2 is a similar View in another operative position. Fig. 3 is a `partial plan. Fig. 4 is a vertical section on the line 4--4 of Fig. 3.

Fig. 5 shows the parts of the apparatus illustrated in Fig. 4 in another operative position. l Figs. 6-11 are `detailed views. u The table AI for the wrapper consists of a plate provided with sieve-like openings beneath which a suction head housing 2 is ,mounted The suction head .housing is connected by means of a pipe 3 with a fan 4 which is driven by a belt. 5 and a motor 6. The suction head housing is carried by a projecting arm G .attached to the machine frame G. The table I, the special form of which is shown in Fig. 3, is provided with four recesses I in which the hereinafter described gripping members engage. The gripping members consist of a bar l, which is carried by two arms 8. The latter are carried on levers I0 mounted on the machine frame at 9. On the arms 8, which are mounted on the upper end of the lever I0, there is Yprovided an axle Il on which a support I 2 is rigidly mounted for movable to-ng jaws I3 which consist of two plates attached to the support I2, each of which plates has two l rests on a pin .I 8 provided on the machine frame.

When the lever I0 swings to the right as indicated in Figs. 1 and 6, the roller .comes into contact with the plate I`1. This causes the lever I4 and the jaws I3 connected therewith to swing out against the tension of a spring I9 in such manner that the mouth of the tongs opens. When the lever I0 has arrived in its extremel right-hand position in which, as shown particularly in Fig. 4, the front edge o-f the wrapper U :comes into position between the opened mouth of the tongs, the roller I5 on the lever 'I4 comes into the range of a recess Il provided in theplate I1. The roller on the lever I4 is thereby released and is able to swing into the position indicated in full lines in Fig. 7. At the same time the wrapper is held firmly, under the action of the spring I9, between the jaws I3 and 'l of the tongs. When the lever I0 swings back into the position indicated in Fig. 2, the wrapper is carried along and withdrawn on to the depositing table which is subjected to moderate suction action, the wrapper at the same time is tightened and smoothed (see Fig. 5). When the lever Ill swings back into the position indicated in Fig. 7, the roller I5 comes into contact with the bottom side of the plate I1, because the plate is moved correspondingly upwards.

When the lever Ill swings back, the wrapper is passed over the rolling apron 2U, the latterbeing attached, in known manner, on one side to the rolling table 22 at 2|. On the other side the rolling apron is passed over the roller 23 and is attached to the roller 24 flexibly if desired. The known trough in the rolling table is formed on the one hand by a jaw 25 which is carried by a tubular member 26 provided with a collar 26. Into the tubular member 26, which is adapted to be displaced axially in a housing 21 attached to the machine frame G, there is passed a rod 28. A sleeve 29 is pivotally mounted on the rod 28, and with this a lever 38, which is pivotally mounted on the machine frame at 3l, engages. The lever 30 is provided with a roller 32 which comes into contact with a cam disc 33. The camdisc is mounted on a shaft 34 to which a spur wheel 35 is also attached. I'he spur wheel 35 engages with a corresponding spur wheel 36 which is mounted on the driving shaft 31 of the machine, this shaft 31 being connected by means of a belt pulley 38 and a driving belt 39, with the electro-motor 6. On the driving shaft 31 is mounted a crank disc 40, the crank pin 4I of which engages in a cam slot I8' of the lever I0. 'I'he other side of the trough is formed by a plate 42, which is pivotally mounted on an axle 43, which is provided on the horizontal part of the jaw 25. An arm 42 of the plate 42 protrudes into a recess in the jaw 25 and is pressed by a spring 44 against the head 28 of the rod 23.

When the tongs 1, I3 have arrived in the position indicated in Fig. 8, the rolling table trough 25, 42 is brought into the position indicated in Fig. 8. This is effected by means of the lever 30, in that, between the upper adjusting nuts 29 of the sleeve 29 and the collar 26 of the tubular member 26, a spring 45 is inserted. The tubular member 26 and the jaws 25 connected therewith are therefore upwardly displaced by the lever 30 without the rod 28 being displaced in the tubular member 26 until the collar 26' rests against the bottom of the housing 21. In this position a spring-controlled stop 41 which is provided in a pressure chamber 48 is pressed back in such manner that it is placed flexibly on, and thereby firmly holds, the wrapper U located on the rolling apron 20. But at the same time a projection I4 provided on the lever I4 strikes against a stop consisting of an adjusting screw 49 whereby the mouth of the tongs is opened so that the wrapper now lies freely on the rolling apron 28, held only by the flexible pressure member 41. Now while the plunger 59 thrusts the compressed tobacco P from the pressure chamber 48, the sleeve 29 is raised owing to its further movement into the position indicated in Fig. 9. As the tubular member 26 and the jaws 25 have attained their highest position the further movement of the lever 30 is utilized, while overcoming the spring 45, to displace the rod 28 upwardly in the tubular member 26. This causes the plate 42 to be moved outwards so that the ller can be introduced without difliculty. During this operation, the spring-controlled pressure member 41 holds the wrapper firmly so that it cannot slip when the filler is introduced.

As soon as the plunger 56 has returned to its upper position, the lever 3S! is guided downwards by the cam disc 33 which rst of all causes the plate 42 to move inwardly (see Fig. 10). Then y the trough consisting of the jaws 25 and the plate 42 is moved downwards again so that the rolling apron passed over the upper surface of the jaw 25 rests on the rolling table 22. Then the lever I!) is swung to the right as indicated in Fig. 2, whereby a roller 5I mounted on the lever IIJ comes into engagement with the rolling apron 28 in such manner that the bunch is in a loop formed behind the roller 5I. Fig. 11 shows the precise moment in the operation when the filler P which is for the greater part covered by the wrapper, is withdrawn from the trough, which is done by a slight movement of the plate 42. By this means the corresponding end of the wrapper is placed rmly about the filler P. As soon as thev bunch formed in this manner has reached the end of the rolling table, it is deposited in known manner in a receiving trough or the like. These receiving troughs may be attached to a conveyor chain which feeds the bunch forward to the place where it receives further treatment, for instance to the rolling device in which the wrapper is applied. In its extreme right-hand position the roller I5 of the movable tong jaws comes into contact with the plate I1 so that when it swings into its extreme outermost position, the tongs `with open jaws come into the range of the depositing table I whereupon the operation is repeated.
